Key Parameters

Substitute Part Grouping Explanation

Substitution of the RCS2012F5234CS is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Resistance value: 5.23 MOhms
• Tolerance: ±1%
• Power rating: 0.125W (1/8W)
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C

Mechanical Parameters:

• Package format: 0805 (2012 Metric)
• Physical dimensions: 0.079" L x 0.049" W (2.00mm x 1.25mm)
• Number of terminations: 2

Compliance Parameters:

• RoHS3 compliance
• Moisture Sensitivity Level 1 (Unlimited)
• REACH Unaffected status

The CRCW08055M23FKEA from Vishay Dale meets all electrical and mechanical equivalence criteria. This substitute maintains identical resistance, tolerance, power rating, temperature coefficient, and operating temperature specifications. Both components utilize thick film construction and are packaged in the 0805 (2012 Metric) format with identical termination configuration.

Parameter Comparison

Engineering Selection Recommendations

Both the RCS2012F5234CS and CRCW08055M23FKEA are active production components with full RoHS3 compliance and REACH Unaffected status, making either suitable for new designs and existing applications requiring regulatory compliance.

The RCS2012F5234CS features anti-sulfur and moisture-resistant construction specific to Samsung's thick film technology. The CRCW08055M23FKEA carries AEC-Q200 automotive qualification, indicating suitability for automotive applications with enhanced reliability requirements.

Selection between these components should be based on application-specific requirements: the Samsung part for general industrial applications requiring anti-sulfur protection, or the Vishay Dale part for automotive and mission-critical applications where AEC-Q200 qualification is specified or preferred.

The maximum seated height difference of 0.006" (0.16mm) between components is negligible for standard PCB assembly processes and does not impact interchangeability in typical circuit designs.

Frequently Asked Questions (FAQ)

Q: Can the CRCW08055M23FKEA directly replace the RCS2012F5234CS in existing designs?

A: Yes. Both components share identical electrical specifications (5.23 MOhms ±1%, 0.125W, ±100ppm/°C, -55°C to 155°C), identical package format (0805/2012 Metric), and identical termination configuration (2 terminations). The maximum seated height difference of 0.006" is within standard PCB assembly tolerances and does not affect circuit performance or board layout.

Q: What is the significance of AEC-Q200 qualification on the CRCW08055M23FKEA?

A: AEC-Q200 is an automotive industry standard qualification that certifies component reliability under automotive operating conditions. This qualification is relevant only if the application requires automotive-grade components. For non-automotive applications, this certification does not impact functional equivalence.

Q: Are both components RoHS3 compliant?

A: Yes. Both the RCS2012F5234CS and CRCW08055M23FKEA are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements for electronic components.

Q: What is the difference between anti-sulfur construction and standard thick film construction?

A: The RCS2012F5234CS incorporates anti-sulfur and moisture-resistant features specific to Samsung's manufacturing process. The CRCW08055M23FKEA uses standard thick film construction. Both achieve identical electrical performance and operating temperature specifications. The anti-sulfur feature on the Samsung part provides additional environmental protection in corrosive atmospheres, but this does not affect electrical equivalence for standard applications.

Q: Can these components be used interchangeably in PCB assembly?

A: Yes. Both components are packaged in 0805 (2012 Metric) format with identical footprint dimensions (0.079" L x 0.049" W / 2.00mm x 1.25mm). Standard pick-and-place equipment and reflow soldering processes accommodate both components without modification.

Q: What is Moisture Sensitivity Level 1?

A: MSL 1 (Unlimited) indicates that the component has unlimited shelf life and requires no special moisture control during storage or handling. Both components carry this rating, eliminating moisture-related storage or handling constraints.
